Portability doesn't mean "the code wiil compile
on every platform and C compiler in the world".
Most platforms will have their own packaging
systems and directory hierarchy, so *some* changes
will have to be made every time code is ported; as
long as the necessary changes are obvious, I don't
see that there is any real problem.
